‘Little leaf' of mango is due to the deficiency to India of Zinc.
The leaves become small and narrow with leaf margins bent upwards or downward. Inter nodal length is reduced drastically and a twig with crowded leaves gives a rosette appearance.

The biocide used in vase solution for the preservation of flowers is 8-HQC.
A standard preservative solution containing 2% sucrose and 200 mg dm^-3 citrate or sulfate of hydroxyquinoline (8-HQC or 8-HQS) is often used to prolong the vase life of cut flowers.
The 8-HQC is a very important and effective biocide used in the floral industry. Thus, incorporating 8-HQC either in the preservative solution or as a pulse treatment would restrict microbial growth and subsequent vascular blockage and thus promote water uptake.
